I've this situation: a form where are managed "students", for example, and It's necesary to control when a student has "classes" asociated, and if its the case, show in a window a multirecord with those classes.

To do so, i am trying this: when a student's record is changed (WHEN-VALIDATE-RECORD), i check by a SELECT if has classes, if so, i create a cursos to insert in to a multirecord_non_database_blobk those classes and then a GO_BLOCK to show the canvas associated eith that block.

Then problem is that I can't execute a GO_BLOCK in a WHEN_VALIDATE_RECORD trigger, because its restricted.

Anyone knows someway to "invalidate" that restriction, or almost, to something similar to simulate it?
